Abstract: A game apparatus calculates a gravitational vector Vg, which represents a gravitational direction viewed from an input device, based on operation data. Then, a motion acceleration vector VA, which represents an acceleration applied by a motion of the input device, is calculated based on an acceleration represented by acceleration data and the gravitational vector Vg. The gravitational vector Vg is corrected such that the motion acceleration vector VA approaches a motion acceleration (vector VA?) satisfying a relationship with an angular rate (vector V?) represented by angular rate data, the relationship being predefined between the motion acceleration and the angular rate for the input device making a predetermined motion (rotational motion). Furthermore, the game apparatus calculates an orientation of the input device corresponding to the corrected gravitational vector.

Abstract: A game apparatus includes a controller provided with an acceleration sensor for detecting accelerations on at least two axes orthogonal to each other. When playing a game, the controller is given a rotating operation so as to rotate around an axis orthogonal to the two axes. The accelerations on the two axes detected according to the rotating operation are converted into a point on a two-dimensional coordinate system. An angle of each converted point is calculated, and an angle change is also calculated. Based on the angle change corrected to change smoothly and a previous correction angle, a present correction angle is calculated. Game processing according to the correction angle is performed, and a game object is moved by an amount corresponding to the correction angle, for example.
